SubjectRe: [Linux-fbdev-devel] [PATCH] nvidiafb: allow ignoring EDID info

I'd gladly do it, if I knew how to retrieve it ... because apparently,
get-edid doesn't work, even though both the nv driver for X and
nvidiafb manage to retrieve it.

This is the output from get-edid

Anything else I can try?
